1) most spam I get doesn't come from spammers.
   It comes from (unwitting?  witless?) relays.
   And if they drop when the see it, it's good training.
   I'll put it into my sendmail greeting.

2) I'm all for very quietly sending a 400 error
   and letting them try over and over again.
   quiet meaning sendmail doesn't fill logs with it.
   The lag/delaying tactics (and the cute new start
    with itty bitty TCP windows that just came in)
   doesn't really do it for me.  That's just revenge.
   If you want it, then that's your choice.
